How to Contact McKesson Customer Service

Trying to reach McKesson support can feel like navigating a maze without a map. Whether you are a pharmacist dealing with a "billing dispute," a hospital admin facing "technical support" glitches on McKesson Connect, or just tracking a delivery, it is rarely straightforward. You can try their main phone line, dig through the online portal, or check Visit McKesson. It reminds me of those viral TikToks reenacting the nightmare of US healthcare administration. Just endless loops. We dug through Better Business Bureau complaints to find the actual ways to get a human.

Before You Call: What to Have Ready

Don't waste your time. Before you call, make sure you have your account number and the email you signed up with handy. Trust me, they will ask for it immediately.

  • Your McKesson Account Number: Usually a 6-8 digit code found on your invoice.

  • DEA License Number: If you are a pharmacy ordering controlled substances.
  • Exact Error Code: If the portal is crashing, write down the code (e.g., "Error 403").
